"""Regression tests for LiteLLM package data in frozen release binaries.

Azure OpenAI and ``OPENSRE_LLM_TRANSPORT=litellm`` import ``litellm`` at runtime.
LiteLLM reads JSON price/context files from its package directory on import; the
release PyInstaller build must bundle them under ``_internal/litellm/`` or the
binary crashes with ``FileNotFoundError`` (see issue #3631).

Workflow contract assertions live in ``tests/github_ci/test_release_workflow.py``.
